Which parameter has the value 160?

Which parameter has the value 160?

• A. V window
• B. Vfe 1
• C. Vb below 10k
• D. Vb above 10k

Answer: (A)

V window is a fixed speed value on the ERJ 175 limits that defines the operating window within which the airplane’s structural limits are guaranteed. Here, that fixed value is 160 knots, so it matches the given number. The other speeds don’t stay constant: Vfe 1 is a flap-extended maximum speed and is a specific value that is not 160 in this context; Vb speeds depend on altitude (there are different numbers for below 10k and above 10k) and thus aren’t a single fixed value. So the only parameter that reliably equals 160 in the reference data is the V window.
